Electrodeionization

Electrodeionization (EDI) is a water treatment process that removes ionizable species from liquids using electrically active media and an electrical potential to effect ion transport. It differs from other water purification technologies such as conventional ion exchange in that it is does not require the use of chemicals such as acid and caustic. EDI is commonly used as a polishing process to further deionize Reverse Osmosis (RO) permeate to multi-megohm-cm quality water
